We have many times extolled, and documented, the rather vast utility of Methane.
It is, for instance, a key component of "tri-reforming" technology, such as described best and most lately, as we've documented, by scientists at Penn State University, wherein it can be reacted with reclaimed Carbon Dioxide and made thereby to synthesize liquid hydrocarbons.
Further, in fact, via separate dispatch today, we are sending along report of: United States Patent Application: 0100105962; "Hydrogenation of Carbon Dioxide into Syngas Mixture", wherein Saudi Arabian and Texas scientists, in the employ of the oil industry, disclose that Methane can be utilized in the conversion of Carbon Dioxide into a synthesis gas suitable for catalytic condensation into Methanol and other hydrocarbon fuels.
